CPU WATER BLOCK
EK-Classic CPU Water Block
115x /20x x D-RGB

This product is intended for installation by expert users only. Please
consult with a qualified technician for installation. Improper installation may
result in damage to the equipment. EK assumes no liability whatsoever,
expressed or implied, for the use of these products, nor their installation.
The following instructions are subject to change without notice. Please
visit our website at www.ekwb.com for updates. Before the installation
of this product, please read important notice, disclosure, and warranty
conditions printed on the back of the box.
Before you start using this product, please follow these basic guidelines:
Carefully read the manual before beginning with the installation
process.
Remove your graphics card from the computer for the safest
mounting process and to prevent any possible damages to your GPU
or graphics card circuit board (PCB).
EK Fittings require only a small amount of force to screw them
firmly in place since the liquid seal is ensured with the rubber O-ring
gaskets.
The use of quality market-proven corrosion-inhibiting coolants is
always strongly recommended for any liquid cooling system, and
mandatory for nickel-plated water blocks.
Do not use pure distilled water as a cooling liquid! For best results,
EK recommends the use of EK-CryoFuel Coolants.
Make sure to bleed air out of your water block thoroughly, in order to
reach optimal performance.

INSTALLING THE WATER BLOCK
STEP 2
Cleaning the CPU: Wipe the CPU’s contact surface with a
nonabrasive cloth or Q-tip (as shown in the image).
Applying thermal compound: On the clean CPU IHS - Integrated
Heat Spreader, apply a blob or line of enclosed thermal compound
(see sample image on the left).
EK recommends the quantity of about two rice grains of
thermal compound. There is no need to cover the whole
IHS. Applying too much thermal grease will disrupt cooling
performance!
LGA 20113 SOCKET MOTHERBOARDS
STEP 1
Prepare the foil bag with the mounting mechanism that is enclosed
with the CPU water block.
Install four (4) specific LGA 2011 M3 thumb screws into four threaded
stubs on the LGA 2011 socket’s integrated latch mechanism (ILM).
The screws are to be installed using no tools (i.e., pliers).
It is recommended to remove the motherboard from the
chassis before proceeding with the CPU water block
installation due to space constraints in various PC cases.

STEP 3
Remove the sticker from the water block cold plate.
Align the water block over the mounting screws on the LGA 2011(-3)
motherboard with a pre-installed CPU.
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
Place an enclosed compression spring and a thumb nut over
each M3 thumb screw. Start fastening two thumb nuts at a time,
preferably in a cross pattern, but do not tighten them fully until all
four are partially screwed in. Then - using your fingers only - screw
in all four thumb nuts until you reach the end of the thread.

Tighten the fitting barbs in a clockwise direction until the gasket
underneath is compressed.
The installation of the CPU water block is now complete.
With EK-Supremacy Classic series water blocks, it is
mandatory to use the port closest to the center of the water
block as the INLET port. Mixing these ports up may result in
poor thermal performance of the water block.

STEP 1
If already installed, please remove the motherboard from the computer
case. Place it on an even surface with the front facing downward.

STEP 2
Preparing the Backplate Rubber Gasket
The enclosed rubber gasket is an essential part of the backplate and
mounting system, and therefore must be used every time you install
this water block on the motherboard.

STEP 4
Install four (4) M3 thumb screws into your motherboard. It is mandatory
to put a plastic washer underneath each M3 thumb screw. Tighten the
screws to the metal backplate until you reach the end of the thread.
Using tools (i.e., pliers) is not recommended.

STEP 3
Install the backplate rubber gasket and place the metal backplate
for Intel® LGA 115x/1200 socket to the back of your motherboard
ribbed side up (facing away from the motherboard). Align the holes
on the motherboard with holes on the rubber gasket and backplate.
Make sure to orientate the rubber gasket to fit past the
CPU socket ILM backplate. On certain ITX form factor
motherboards, the rubber gasket may need to be trimmed
with household scissors.
Using one hand, carefully rotate the motherboard assembly with the
front side facing up while holding the backplate and rubber gasket in
place with the other hand.

STEP 6
Align the water block over the mounting screws on the LGA
115x/1200 motherboard with a pre-installed CPU.
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
Place an enclosed coiled spring and a thumb nut over each M4
thumb screw. Start fastening two thumb nuts at a time, preferably in
a cross pattern, but don’t tighten them fully until all four are partially
screwed in. Then – using your fingers only – screw in all four thumb
nuts until you reach the end of the thread.

CONNECTING THE D-RGB LED STRIP
D-RGB LED Connector
STEP 1
Connect the 3-pin D-RGB LED connector from the Water block’s LED
light into the D-RGB (Addressable) HEADER on the motherboard.
The LEDs will work if the pin layout on the header is as follows: +5V,
Digital, Empty, Ground.
Please ensure that the arrow indicated on the connector
is plugged into the +5V line, as indicated on your
motherboard. If you connect LEDs to the 12V RGB header,
it will damage them.
